  • Fiber optic sensor
    Patent number: 5900215
    Abstract: A method is provided for manufacturing a fiber optic sensor for detecting or measuring a parameter of interest in a sample fluid, including pH, concentration of dissolved gases such as O.sub.2 or CO.sub.2, and the like. The sensing chemistry is affixed to the distal end of an elongated optical fiber by way of an adhesive layer typically comprised of an acrylic adhesive composition. Novel optical sensors, fabricated using the aforementioned method, are provided as well.
    Type: Grant
    Filed: May 14, 1997
    Date of Patent: May 4, 1999
    Assignee: Optical Sensors Incorporated
    Inventors: Kevin R. Seifert, Laurie Lynch, Debra K. Johnson, Jonathan Kalla, William Fowler
